The Muncie SH8 Series Power Take-Off, part number SH8B-U6809-P1BX or SH8BU6809P1BX, is an air-shift-only PTO built for high-torque applications. It bridges the gap between lighter and heavier Muncie series, fitting most popular transmissions through 17 available input gear sets. The 8-bolt cast iron housing mounts securely without exposed air cylinder hardware, keeping the installation clean and compact. Five speed ratios and 12 output shaft options cover a wide range of hydraulic pump configurations. Rated at up to 76 intermittent HP and 400 lb-ft intermittent torque at 1,000 RPM on the faster speed ratios, this unit handles demanding vocational-truck duty cycles.
